It's OK to call SegSetGrey on a segment with an empty rank set so long as you are not actually setting it to be grey for any traces, so correct the AVER accordingly.

This was the result of noticing a large number of SetSetGrey events that set the segment to the same greyness when scanning ambiguous references.

Adding a pseudo-target "find-puns" which, on FreeBSD mostly, prints useful warnings about strict aliasing rule violations.
Fixing more strict aliasing rule violations found by the above.

Now that we're recommending inlining with client code and optimising with -O2 or -O3, we can't afford any bug introduced by the strict aliasing rule.

Abolishing event formats. Each event now has its own structure.
Event parameters are now written directly into the event buffer, rather than being copied twice.

poolamc.c tidy up:
neater implementation of obj1pip (amcReclaimNailed)
neater implementation of amcResetTraceIdStats -- no need for a function any more
delete lots of obsolete temporary diagnostic (superseded by AMCTraceEnd_pageret)
a few more avers (especially on buffer empty)
also revert temporary diagnostic changes in arena.c, config.h, diag.c, global.c
diag.c: fix diag-buffer at 100 screenfuls (200000 chars).
zcoll.c: reinstate Make 50000 with occasional big objs.

zcoll:
- parameterize BigdropSmall for big-obj size and small-obj ref-type, eg "BigdropSmall(big 28000, small A)"
- Park, to avoid all those minor collections. Explanatory comments.
poolamc.c:
- diags: AMCTraceEnd, AMCTraceEnd_perc (new), AMCTraceEnd_pad_med (new),
- AMCTraceEnd: c Segs/Pages Whiten/Reclaim, cPagesRet(ained)
- AMCTraceEnd_perc: percentage of condemned pages retained by ambig refs
- AMCTraceEnd_pad_med: over-detailed calculations of Gain & Loss for Medium segs,
requiring knowledge of size of obj1 in each seg.
diag.c:
- Just show AMCTraceEnd_perc and AMCTraceEnd_pad_med, for zcoll/BigdropSmall's purposes.
Note: poolamc.c now has several episodes of experimental diagnostic in it.
It's time to re-baseline it from an un-hacked version.

Currently: whitenCount & reclaimCount, for diag at AMCTraceEnd.
(These aren't interesting in themselves; next task: calculate more interesting per-trace stats).

Tracer calls PoolTraceEnd() when the trace is TraceFINISHED.
AbstractPoolClass uses PoolTrivTraceEnd -- a NOOP. [mpm.h, mpmst.h, mpmtypes.h, pool.c, poolabs.c]
AMC overrides with AMCTraceEnd, to emit diagnostic on how well the trace went! [poolamc.c]

zcoll.c: BigSmall() command -- creates small, then big, then small object.
poolamc.c: AMCDescribe(): output AMC Seg maps, showing single big object -- a pad -- at end of large-segment.
arena/config/diag: allow output of AMC Seg maps.

More diag:
- new traceSetSignalEmergency;
- new AMCFix_amcSegCreateNailboard and AMCHeaderFix_amcSegCreateNailboard
(note: the other, unreported, route to becoming boarded is because of a (mutator) buffer);
- in traces: show SegBase and zone;
- in TraceStart: show genZoneSets;
- in amcReclaimNailed: show cbpip and cbpad.
zcoll.c:
- sizemethod 1 to Make command: occasionally makes >1MiB objects;
- declare root_table all MPS_RANK_AMBIG.

code (but badness was being masked by the shield cache; see
job001706). ShieldExpose(seg) once, and ShieldCover it once, so
that _all_ .exposed.seg statements are between Expose and Cover.

with ".exposed.seg" statements that require that "seg" (that is:
the 'from' seg) has been ShieldExposed. (Preparatory to fixing
